I've been trying to identify a certain movie that I haven't seen since I was about three feet short. All I can remember is this:

It's REALLY violent. At (possibly the beginning), there's a bunch of 'bad guys' holed upin the windows of a beat up building, having it out with cops parked below. I remember the front lot being really bare, maybe like the Bronx in the 80s/late 70s.

So they're all shooting it out and one guy gets wasted through the window, and this scary looking lady who looks like Anne Ramsey (maybe his mom) freaks out, picks up his gun, a two handed gun, and starts blasting at the cops.

I only remember that one scene because some angry mom shooting cops really struck me. This movie couldn't be any newer than 1993.
